The first part of the project is the fuel testing. This is the uv reactive inert liquid propellant.Stage 1. Remove some ink from a Non-Toxig highlighter pen.Next test under a UV spotlight....and finally, dilute with water...Next stage is to fire streams...
Various designs have been explored to deal with the cable. The method should: - Be able to roll up a 45cm long cable- Have low learning curve- BE self-explanatory- Not block the user's grip- NOT be the weakest link of the stylus (most important!) And...
The very first PCB I assembled was populated using tweezers but it didn't take long to realise that tweezers are not very efficient for a number of reasons: There's not enough space around a component in the tape to get the tips of the tweezers in and...
This is UV ink on normal white paper, with a drawn white, of course the marker pen is 2mm tip . You can use your phone with a QR code to read by looking at this picture. It is my email address as a sample. The edges are not sharp, but my cell phone...
I have had some time during waiting to PCB. So I have made some first lookup at the housing. I have to think about final position of missing components. There is a several option to place the pen socket, like on the front or back. Same problem with...
A couple of more parts turned my plotter into a dot matrix printer. It's for sure no replacement for an inkjet, but another educational tool that visualizes the difference between vector and bitmap graphics. I am utilizing the filament extruder to speed...
I grabbed some simple Hilbert Curve code from this thread: https://stackoverflow.com/questions/7218269/hilbert-curve-analysis And added the ability to export gcode instructions as the recursive function played out. The result is very satisfying as the...
CircuitVideo input comes from composite video source and works as a passthrough. I have used one male and two female connectors to make it easy to connect as a passthrough no matter what cables are available.The LM1881N video decoder chip is an interface...
With a pilot project beginning May 04th 2022 where we will be installing our very first modules, we are working on optimising the development of our prototypes. So far, we've come accross a few challenges (images to be shared later), including: Cracking...
The y-axis is getting radically simpler: Yes, that's the whole thing. Gets rid of a whole lot of parts. Will have to see how this will hold up over time. A marker pen is a very simple thing to make, So I made my own, adding lightness. Edding...
My PCB order was deliverd yesterday.After a bit of soldering and testing - everything works!It feels really good to have some working hardware in the hands.With the battery and the two resistors I made a quick energy measurement of this disposable rechargeable...
If the picture isn't a bit of how I felt when assemlbing these little tricksters than the explanation will. The entire build except for one piece went smoothly. Some parts were no longer being sold so I had to improvise with better newer...
As I'm writing the guide for building and programming this robot, I need a way to test if the instructions make sense and are simple enough. So I've build another brother for µKubik, this time following my own instructions to the letter. It went...
I figured a way to get the full 13 bit resolution of the PWM and now I get the full value range. I figured that my timer counter being 8192 is just a shift of 13 so I can avoid overflow by not shifting up 13 and down 10 but rather just do the entire...
I've been developing the next iteration of ZAViouR and it's first I/O Port. I will be adding a backplane but I want to get the first interface designed and working beforehand. This will enable me to test the connections are in the correct topology etc....
